摘要

Discrete polyesters with cyclic side chains were synthesized

via

iterative growth. Cyclic pendant groups lead to more compact chain conformation and higher glass transition temperature compared to linear analogues

demonstrating topology-property relationships.

Abstract

In contrast to cyclic polymers with ring-like backbones

side-chain cyclization is another intriguing structural feature that has not been extensively studied. In this study

a library of orthogonally protected monomers featuring monocyclic

dicyclic

or tricyclic pendant motifs was designed and prepared based on malic acid derivatives. Polyesters with precise chemical structures and uniform chain lengths were prepared modularly through iterative growth. Meticulous control over the chemical details allows for a close investigation of the topological effects on the polymer properties. Compared to their linear side chain counterparts

the presence of cyclic pendant groups has a significant impact on chain conformation

leading to a reduction in hydrodynamic volume and an enhancement in the glass transition temperature. These results underscore the potential of tailoring polymer properties through rational engineering of side chain topology.
